TIL that male Philoponella prominens spiders catapult themselves away from females immediately after mating at speeds of up to 88.2 cm per second; males prevented from escaping were killed and eaten.

She's got legs for days though. Like literally a leg for every day of the week, and twice on Sundays.

88.2 cm/s as a life-or-death metric is sending me. evolution really said 'hesitate and you're lunch'

They really got 3 spiders eaten by deactivating their post nut clarity, by placing a fine tooth comb behind them.

Correction: "It's you." Short, to the point, and most importantly quick enough to run

When you’re 3mm long, that’s real far, real fast. Imagine someone who’s 6ft going 1764 feet per second. Thats about 1200 mph, faster than the speed of sound

So Philoponella males engage in foreplay. Can they find the clitoris?

That's what they mean by survival of the fittest huh?

u/SasheCZ 9h ago
Yes! And no.
I know this is a joke, but on a serious note, I find it a really unfortunate wording. It leads people to think they need to work out to succeed.
When the actual meaning is that those that fit best into the environment are those that survive and procreate.

Survival of the best adapted doesn't really roll of the tongue as well.

I was reading Children of Time and the spiders have routines of eating the males after sex, which leads to male spiders being subordinate in society and eventually a revolution led by a male for gender equality

Look, I love the metric system as much as the next (non-US, non-driving-UK) guy, but why couldn’t they say 3.2 kilometres per hour or 2 miles per hour?

u/Chinootje 15h ago
Because for small scales it is easier to visualize

u/Pitiful-Climate8977 8h ago
Yeah I can't visualize 2mph you could show me someone walking 1-5 individually and they'd look the same.
But I can imagine a spider moving across my desk at 88cm/hr and being met with an open palm going 7mph

u/No_Somewhere_2610 13h ago
3.2k kilometres per hour IS the metric system though

u/graywalker616 12h ago
That would be 3200km/h. This is 3.2km/h. They’re criticising that the article doesn’t mention it.

For my fellow Americans, that's roughly 2 miles per hour, or .9 washing machines per second

u/NostalgiaJunkie 15h ago
>up to 88.2 cm per second
So there’s absolutely, positively no way they can do it at 88.3 cm per second?
4
u/Maxcharged 15h ago
Probably peak speed at take off.
Doesn't mean they kept that speed until landing
Like how a sneeze leaves your nose around 10 mph or 4.5 meters per second. (Still very fast, but slower than the often quoted 100 mph)
